Patent number: 6725546Abstract: A cutting tool having first and second lever arms with a cutting end and a handle end. A first insert and a second insert are connected to the cutting ends of each of the lever arms. The inserts are removable from the cutting ends of the lever arms, and each of the inserts include multiple cutting edges. When the inserts are connected to the cutting ends of the lever arms and the user pulls the handle ends towards each other, the cutting ends also move toward each other. As the cutting ends move toward each other, the inserts act cooperatively to sever materials located therebetween. When one of the cutting edges of an insert becomes dulled or damaged, the user removes the insert from the cutting end of the lever arm and repositions the insert on the cutting end such that a different cutting edge is revealed for severing materials.Type: GrantFiled: August 5, 1999Date of Patent: April 27, 2004Assignee: Alterra Holdings CorporationInventors: Edgar A.

Patent number: 6530099Abstract: A composite pliers has crossed levers, each including a non-metallic body with an exposed metal cutter blade. The pliers includes strengthening and/or retaining structure around a pivot joint which does not extend into handle portions of the levers. This structure strengthens the pivot joint and can help confine the pliers parts in the event of failure. In one embodiment, each lever has a pivot joint strengthening structure insert molded therein, the structure extending into a jaw portion of each lever and protruding from the non-metallic body to form a workpiece engagement surface, such as a cutting blade. In one form, the jaws have more than one row of teeth with adjacent rows offset from each other. When the pliers is assembled from two identical lever members, each row of teeth on one lever will face the offset row of teeth on the other lever so that the peaks of the teeth on one lever fall within the grooves between the teeth on the opposing row.Type: GrantFiled: July 19, 2000Date of Patent: March 11, 2003Assignee: Snap-on Technologies, Inc.Inventor: Dean J.

Patent number: 6009583Abstract: A pliers-knife combination tool including pivotally connected elongated members. A working region of the tool includes opposed gripping jaws on interior faces of the elongated members and at least one knife edge on an exterior edge of one of the elongated members. Engaging the opposed gripping jaws with each other allow use of the tool as a knife. A method of fabricating the tool includes maximizing the size of the tool for a given size forming machine. Each member is formed separately from the other member to permit sizes as large as possible for the forming dies and machines used. The members are pivotally connected after forming to produce a larger size tool than if both the first and second members were simultaneously formed in a given size forming machine.Type: GrantFiled: November 10, 1997Date of Patent: January 4, 2000Assignee: Swanstrom Tools USA Inc.Inventor: John E. Swanstrom, Jr.
